 DETAILED DESCRIPTION

For purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended, any alterations and further modifications in the illustrated device, and any further applications of the principles of the invention as illustrated therein being contemplated as would normally occur to one skilled in the art to which the invention relates.

FIG. 1 depicts a sliding screen door assembly 100 of the present application. The screen door 106 includes an outer frame 120 and a screen portion 122. The screen door 106 has an inner face 132 which faces an interior of a room and an exterior face which faces outwardly from the room (e.g. faces outside). As will be discussed in depth hereinafter, a plurality of barrier strips can be located around a perimeter of the door to prevent ingress of insects. The sliding screen door assembly 100 can further include a lower threshold 124 extending across a width of the doorway opening 110.

A sliding assembly 104 permits the screen door 106 to slide across a doorway opening 110. The sliding assembly 104 is attached to an upper portion 102 of the screen door 106 and is further attached to a portion of the wall 108. This sliding assembly 104 vertically supports the weight of the door 106. A user can slide the door, for example through use of door handle 130, from a closed position in which an outer perimeter 134 of opposing sides of the door 106 each cover at least a portion of the wall 108, thereby blocking the doorway 110 to an open position in which the door 106 does not impede ingress or egress of the user through the doorway 110.

FIG. 2 depicts the sliding assembly 104 of the present application. The sliding assembly 104 permits the screen door 106 to slide relative the wall 108. In one form, the sliding assembly includes a first track portion 212 and a second track portion 214. The first track portion 212 is slidingly engaged with the second track portion 214 such that the first track portion 212 can move horizontally relative the second track portion 214. In a preferred form, the first track portion 212 and the second track portion 214 are placed in sliding engagement via a plurality of ball bearings 210 which are retained in a channel 216. Although ball bearings 210 provide smooth operation and reduce the force required to open and close the screen door 106, it is contemplated that a variety designs, including rollers, bearings, or cooperating channels can be utilized to place the first track portion 212 and the second track portion 212 in sliding engagement. In one form, the first track portion 212 is attached to the upper portion 102 of the door and the second track portion 214 is directly or indirectly attached to a portion of the wall 108.

In addition to providing vertical support to the door 106, the sliding assembly 104 can be configured to resist horizontal motion (e.g. from wind blowing against the outer frame 120 and pushing the door 106 inward relative a door frame). As is illustrated in FIG. 2, legs 220 and 222 of bearing channels 216 and 218 oppose each other in a manner sufficient to resist pivotal motion (e.g. the roller bearings 210 within the channels cooperate with the legs 220, 222 such that the first track portion 212 cannot pivot relative the second track portion 214). Although one specific sliding assembly 104 has been described in detail, it is contemplated that various sliding assemblies 104 can be utilized to provide vertical support to the door 106 and permit the door to slide between an open position and a closed position across the doorway opening 110.

Referring now to FIGS. 3A and 3B, a cut-away view an upper portion of a sliding screen door assembly 100 is depicted. As is illustrated, the sliding screen door assembly 100 includes an outer frame 120, the sliding assembly 104 coupled to the outer frame 120, a barrier strip assembly 306 disposed between the outer frame 120 and a forward frame 309, and a screen retention assembly 308. The upper portion 102 of the outer frame 120 includes a receiving, portion 305 configured to receive the sliding assembly 104 therein. To permit the sliding operation of the screen door 106 across the doorway opening 110, the sliding assembly 104 is connected to the receiving portion 305 and to a wall portion 108. In one form, the first track portion 212 of the sliding assembly is fixedly connected to the receiving portion 305.

A forward flame 309 can be located forward of the sliding assembly 104. The sliding assembly 104 is fixedly connected to the forward frame 309. Utilizing the sliding assembly described in FIG. 2, the second track portion 214 is connected to the forward frame 309. In this form, the sliding assembly 104 permits the sliding screen door 106 to slide relative the forward frame 309. The forward frame 309 is coupled to the wall 108 adjacent the doorway 110. The forward frame 309 can be coupled to a header of the doorway 110 and can span the doorway 110, or in some forms, the forward frame 309 can act as the header depending upon the design parameters of the specific application.

As will be appreciated, the forward frame 309 suspends the sliding screen door 106 outward from the doorway 110 such that the sliding motion of the sliding screen door 106 is unimpeded by the sides of the doorway 110. In this manner, the sliding screen door 106 slides in front of a surface of the wall 108 between a closed position in which the sliding screen door 106 blocks the doorway opening 110 to an open position in which a user may pass through the doorway opening. When the sliding screen door 106 is slid to a closed position, the upper portion 102 of the outer frame 120 can almost completely hide the sliding assembly 104, such that only the outer frame 120 of the sliding screen door 106 is visible from inside the room. This central positioning of the sliding assembly 104 relative the doorway opening 110 can permit the sliding screen door 106 to be slid open to the right or the left of the doorway opening.

However, it is contemplated that the sliding assembly 104 can be fixedly connected to the wall 108 in a variety of locations. For example, the sliding assembly 104 can extend to the left of the doorway. In this form, when the sliding screen door 106 is slid to a closed position across the doorway 110, a significant portion of the sliding assembly 104 may be visible; however, when the sliding screen door 106 is slid to an open position, the outer frame 120 of the sliding screen door 106 can almost completely hide the sliding assembly 104. As would be understood, the sliding assembly 104 can be mounted to the right of the doorway opening 110 such that the sliding screen door 106 will open to the right. Additionally, the sliding assembly 104 could be attached to the wall 108 above the top of the doorway 110. Although specific mounting locations have been discussed, depending upon the requirements of the specific application, it is contemplated that the sliding assembly 104 can be attached to the wall 108 surrounding the doorway 110 in any manner such that the sliding assembly 104 allows the sliding screen door 106 to slide in front of a surface of a wall between a closed position in which the sliding screen door blocks the doorway opening 110 to an open position in which ingress and egress through the doorway opening 110 are permitted.

The outer frame 120 of the screen door 106 includes a screen retention assembly 308 to retain the screen 122 to the outer frame 120. In one form, the screen 122 is replaceably retained to the outer frame 120 through the screen installation system taught in U.S. Pat. No. 6,378,267, which is incorporated herein by reference. Referring to FIG. 5, this screen retention assembly 308 includes a mounting rib 301 projecting from the outer frame 120 of the screen door 106. This mounting rib 301 extends along an inner perimeter of the outer frame 120. The screen 122 is retained to the mounting rib via a trim mold 303 which includes a channel 504 and retention barbs 506 which are configured to mate to the mounting rib 301 and retain the screen 122 therebetween.

A barrier strip assembly 306 protects against the ingress of insects into the protected enclosure. FIG. 4 depicts an enlarged view of the barrier strip assembly 306. The barrier strip 404 is a semi-flexible member which extends along a width of the sliding screen door 106 and provides an insect resistant seal between the outer frame 120 of the door and the forward frame 309 when the sliding screen door 106 is in a closed position. Although the barrier strip 404 can be constructed of various materials including but not limited to polymers, the barrier strip 404 is depicted as being of a felt construction. A barrier strip retention portion 402 extends outwardly from the outer frame 120 toward the wall 108. The barrier strip retention portion 402 defines a barrier strip receiving channel 307. The barrier strip 404 projects outwardly from the barrier strip receiving channel 307 and extends to an end 406 which presses against the forward frame 309. As will be understood, the width of the barrier strip 404 should be sufficient to traverse the space between the outer frame 120 and the front face 309 or wall 108, depending upon the specific mounting of the sliding screen door 106.

In one form, the barrier strip receiving channel 307 can be formed in a T-shape. In this form, the barrier strip 404 includes outward projections 410 which are received by and retained within the barrier strip receiving channel 307. The barrier strip 404 can include tapered walls 408 which taper outward along a length of the barrier strip 404. This taper can aid in the sealing engagement of the barrier strip 404 within the barrier strip receiving channel 307 and can also aid in the installation of the barrier strip 404 within the barrier strip receiving channel 307. Although a specific barrier strip assembly 306 has been described herein, it is contemplated that the barrier strip 404 assembly can take various forms such that the barrier strip forms an insect resistant seal between the outer frame 120 of the sliding screen door 106 and the forward frame 309 or the wall 108, depending upon the mounting of the sliding screen door 106 thereto, when the sliding screen door 106 is in a closed position.

Referring back to FIGS. 3A and 3B, a first barrier strip assembly 306 is located above the sliding, assembly 104. The sliding screen door assembly 100 can further include a second barrier strip assembly 306 located below the sliding assembly 104. The placement of barrier strip assemblies 306 on opposing sides of the sliding assembly 104 provides resistance against the entrance of insects to an interior of the dwelling. Moreover, barrier strips can additionally be utilized to prevent insect ingress through the sides of the door. For example, as is illustrated in FIG. 1, a barrier strip 128 can be mounted on the wall 108 on opposing sides of the sliding screen door 106. When the sliding screen door 106 is in a closed position, in which the outer perimeter 134 of opposing sides of the door 106 each cover at least a portion of the wall 108, the outer frame 120 will contact the barrier strips 128 on opposing sides thereby providing resistance to insect penetration. Barrier strips 128 can take a form similar to barrier strips 306.

Although it is contemplated that various techniques can be utilized to form the outer frame 120, in one form an extrusion process is utilized. In this manner the mounting rib 301, and where desired the barrier strip receiving channels 307, can be integrally formed with the outer frame 120. Additionally, the use of an extrusion process permits hollow cavities 322 and 324 to be located within the outer frame 120 and upper front frame 309. These hollow cavities 322 and 324 can reduce the amount of material utilized to create the sliding screen door assembly 100 and can reduce the weight thereof.

Referring now to FIGS. 6 and 7, the sliding screen door assembly 100 can further include a lower threshold 124. This lower threshold 124 is located vertically below the sliding screen door 106, such that a lower portion 126 of the sliding screen door 106 slides in a channel 606 of the lower threshold 124. The lower threshold 124 extends at least along a portion of the doorway opening 110. Opposing walls 608 of the channel 606 resist any forward or rearward movement of the sliding screen door 106. The engagement of the lower portion 126 of the sliding screen door 106 by the channel 606 provides additional resistance to pivotal motion of the sliding screen door 106. As will be appreciated by one of ordinary skill, the pivotal resistance provided by the lower threshold 124 in addition to the pivotal resistance provided by the sliding assembly 104 yields a sliding screen door 106 which is suitable for use in windy climates. Opposing outer sides 604 of the lower threshold 124 are tapered to reduce the risk of tripping on the lower threshold 124 and can enable the structure to remain handicap accessible.

Barrier strips can be integrated with the lower threshold. Barrier strips 602 and 610 are provided to provide an insect resistant barrier between opposing sides of the door and the opposing walls 608 of the channel 606. Although these barrier strips 602, 610 can take various forms sufficient to resist insect penetration through the threshold, barrier strip 602 is depicted having a barrier strip retention channel 307 located in the lower portion 126 of the sliding screen door 106 with barrier strip 404 extending therefrom. The barrier strip 610 is depicted as being a strip of felt 610 extending along a length of the wall 608 of the threshold 124.
